Note: Other types of Dichroic Filters are available upon request.

Dichroic Filters would reflects a range of wavelength and transmit others, a longpass dichroic mirror is highly reflective below the cut-on wavelength and highly transmissive above it, while a shortpass dichroic mirror is highly transmissive below the cutoff wavelength and highly reflective above it. Variety types of Dichroic Filers are available in Hangzhou Shalom EO: longpass, shortpass, bandpass, bandblocking and colour correction types over a range of wavelengths. Dichroic shortpass and longpass filters can also act as hot and cold mirrors respectively. 

Dichroic Filters are widely used to separate color in CCD imaging, digital projection, light show, machine vision, and printing. These filters allow only a portion of the visible spectrum to pass and reject (reflect) the rest.
